The exit-lanes for a left-turn (EFL) is an unconventional method of organizing traffic for left-turns at signalized intersections. In this paper, we propose a nonlinear optimization model to minimize delay by establishing a delay-time diagram for the left-turn traffic when the left-turn traffic is non-oversaturated, considering the relationship between the pre-signal start node of the exit-lanes for a left-turn and the queuing dissipation time of left-turn vehicles. Model validation is performed with example calculations to compare and analyze each operating index and fleet type after signal timing optimization of intersection lane borrowing left-turn lanes. The results show that compared with the conventional left-turn lane, the average delay of vehicles operating with the model decreased by 15.7%, exhaust emission decreased by 11.4%, and capacity increased by 65.7%. The model can support EFL pre-signal design, where signal control is related to queue dissipation time. In practice, a well-designed pre-signal control scheme based on traffic volume can improve capacity and reduce emissions while minimizing average vehicle delays.

“…One of the most favourable aspects of CA simulation is that it can extract the features from complex systems and then represent the systems using abstract forms for subsequently analysing and solving the relevant problems (Chowdhury et al, 2000; Helbing, 2001; Chen and Wang, 2015, 2016; Bao et al, 2018; Yang et al, 2019). The applications of CA modelling are very diverse in transportation fields ranging from motor vehicles, bicycles, pedestrians, trains, airplanes and ships (Naito and Nagatani, 2012; Rahman et al, 2013; Chen et al, 2019c; Yi et al, 2020), but research on ship traffic flow based on CA modelling is in its infancy and there have so far been very few research achievements. However, the related theories and applications have developed rapidly (Huang et al, 2019; Zhou et al, 2019).…”

In busy waterways, spatial-temporal discretisation, safe distance and collision avoidance timing are three of the core components of ship traffic flow modelling based on cellular automata. However, these components are difficult to determine in ship traffic simulations because the size, operation and manoeuvrability vary between ships. To solve these problems, a novel traffic flow model is proposed. Firstly, a spatial-temporal discretisation method based on the concept of a standard ship is presented. Secondly, the update rules for ships’ motion are built by considering safe distance and collision avoidance timing, in which ship operation and manoeuvrability are thoroughly considered. We demonstrate the effectiveness of our model, which is implemented through simulating ship traffic flow in a waterway of the Yangtze River, China. By comparing the results with actual observed ship traffic data, our model shows that the behaviours and the characteristics of ships’ motions can be represented very well, which also can be further used to reveal the mechanism that affects the efficiency and safety of ship traffic.

“…Chen S. built an optimization model for an EFL intersection to improve signal timing and traffic flow operations [28]. Chen Q. developed a cellular automaton model for EFL signalized intersections and verified the model via field data [29]. Liu proposed a modified shockwave-based method for estimating the maximum left-turn queue length for an EFL intersection and proved that the red time duration and offset between the main and pre-signal greatly affect the queue length [30].…”

Analysis of a Signalized Intersection with Dynamic Use of the Left-Turn Lane for Opposite through Traffic

et al. 2020

For signalized intersections with a quantitative imbalance between the approach and exit lanes, this study proposes a method for the dynamic use of the left-turn lane for opposite through traffic to improve the efficiency of the signalized intersection. The complete scheme of this method mainly consists of three parts: the location routes of the dynamic lane, the temporal scheme, and the spatial scheme. To demonstrate the effectiveness of this method, a simulation scheme comparing the intersection with and without the dynamic lane is designed using VISSIM. The parameters of the simulation model, including the traffic simulation environment parameters and built-in VISSIM models, are calibrated by the field data collected from an intersection in Nanjing, P. R. China. The results of the simulation indicate that this method decreases the average delay and average queue length of the intersection effectively for the intersection with a quantitative imbalance between the approach and exit lanes under the conditions of different through volumes or left-turn ratios. The maxima were 46.9% (average delay) and 68.3% (average queue length) for all situations. Lastly, some suggestions are presented for the application of this method.
